Unique Broadband Over Powerline Project Planned For Mosques
Lucas123 writes "Broadband over powerline (BPL) provider Velchip is heading up a project that will offer 60 million very unique network users an unlimited high speed Internet connection of 224Mbps at a cost of only around RM5 ($1.58) per user per month. That's the cheapest, fastest internet connection in the world. The network is slated for use in the $14 billion 'Smart Mosque' project, which will be rolled out over three years in Indonesia and will link together 400,000 mosques. To add some perspective, in the US Verizon FiOS currently offers up to 30 Mbps downloads and 5 Mbps uploads starting at $42.99 a month. BPL modems use existing electrical power lines to deliver high speed Internet access and data transmission."
Well it's not clear from the article if it's 224Mbps for all 60 million users. Also, the premises could have 224Mbps locally, but the end to end a fraction of that.
While this will no doubt allow the ISP to deliver cache/proxy data very quickly, it will not be financially viable to provide very fast live-internet down this pipe. E.g anything that can be classified as a web-application will probably still be quite average/slow speeds.
The price comes about from using an existing infrastructure, as you know the biggest cost in rolling out a network is the transmission medium. (Especially if it's not your expense to maintain it.)
Any power engineer worth his salt knows the power lines can be modeled as an RLC network... creating losses. These have been optimized for low frequencies (50-60 Hz). Once you get above 1 kHz, your signal won't propogate more than 500 feet. 1MHz and you're lucky to get 50 feet. BPL doesn't actually use the copper line as a waveguide, but creates a rude radio transmitter in the GHz range, which can cause all kinds of trouble. The reason they're trying this abroad is that it's already been rejected outright in the US.
